“Light curves and masses of 300+ detached eclipsing binaries from the CREME project”

Abstract 

The Comprehensive Research with Echelles on the Most interesting Eclipsing binaries (CREME) projects aimed to collect high-resolution spectra of about 380 detached eclipsing binaries (DEBs), which mostly do not have literature RV data. From this vast observational material, we were able to estimate the masses of the components of 324 double-lined systems. Since the launch of the TESS mission in 2018, we have been collecting 2-min cadence photometry for the CREME targets through successful GI proposals. As by Sector 80, we obtained data for 330 of them. We are thus now in the process of comprehensively analyzing our targets. In my talk, I will present the recent status of the CREME project and its space photometry counterpart, describe several sub-projects within CREME that focus on specific classes of targets, and draw plans for the future.
